MOTOR.

SPECIFICATION forming part of Letters Patent No. 743,244, dated November 3, 1903.

Application filed April 2, 1903. Serial No. 150.811. (No model.)

To @ZZ whom it may concern.-

Be it known that I, J oHN G. CAELINET, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Motors, of which the following is a specification.

My invention relates to an `improved device for the utilization of fluid under pressure to obtain rotary movement of any desired form of apparatus, having for its object the production of asimple and efficient fiuid-operated motor whereby the reciprocating motion of a plunger or plungers is transformed into rotary motion of a piece or structure designed to be connected to any device to be operated. This object I secure as hereinafter setforth, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of one form of my improved motor, showing it as designed especially for use in connection with a rotary drill. Fig. 2 is a sectional elevation of the motor taken on the line 2 2, Fig. 1. Fig. 3 is a sectional elevation of the motor taken on the line 3 3, Fig. 2. Fig. 4 is a plan view of the motor, taken on the line 4 4, Fig. 1. Fig. 5 is a plan view of the revoluble member of myimproved motor, showing the gripping-levers therefor; and Fig. 6 isa side elevation of my improved motor in position for operating a drill.

In the above drawings, 1 is a casting consisting of two cylinders open at the ends and connected by a substantially circular plate 7 and a portion 17, each of said cylinders being made in two parts held together by bolts 2, said bolts serving also to hold in place bushings`3 and 4, fitting within said cylinders. These bushings are closed at their outer ends and are bored for the reception of a two-part plunger 5, which consists of two` cylindrical end pieces united by an intermediate section 6, which is preferably square in section. The plate 7 extends between extreme portions of the cylinders at a point below the plunger 5, and there are formed on said plate at points in the present instance ninety degrees from the line of action of the plunger lugs 8, which may be made depending and are provided with threaded holes for the reception of headed. bolts 9, serving as j pivots or fulcrums for connecting arms 10 and 10a. These two arms extend from their respective pivots toward each other, and the squared portion 6 of the plunger is recessed for the reception of their ends, there being longitudinally-elongated slots formed in them intermediate of said ends and-the pivots 9, serving for the reception of pins or projections 11, fixed to and projecting from curved levers 12 and 12a, designed to operate within an annular recess 13a, formed in the movable element 13 of the motor. Said movable element is rotatably supported on a projection or trunnion 14, formed integral with and projecting from the plate 7 of the cylindrical casting 1 at right angles to the line of action of the plungers and being retained in position thereon by means of pins l5, which While fastened in the part 13 engage a groove 16, formed in the trunnion 14, it being noted that the lower end of said trunnion is preferably made convex in form, so that its bearing upon the bottom of the cavity in the movable element is of relatively small extent. It is understood that any other desired device may be employed between these two members for reducing the friction.

The curved levers 12 and 12a are so formed that while freely movable within the annular cavity around the axis of, the trunnion 14` their ends carrying the projections 11 are also movable toward or from said trunnion, the

result of this latter actionbeing to cause a portion of the outer side of a lever to contact with the outer side of the cavity, while the inner side of the lever will similarly contact with the inner side of said cavity, so that the lever is caused, when the projection 11 is moved toward the axis of the trunnion 14, to grip and hold rigidly to the movable element 13 and to release said element when it is moved in the opposite direction.

The cylinder-casting 1 has extending between its extremities at points preferably opposite to those united by the plate 7 the portion 17, which has within it passages 18 and 19, communicating with a valve-chest 20 and also with the interiors of the bushings 3 and 4. A bushing 21, having a flange 22, is held in the valve-chest by means of a couplingpiece 23 screwed upon it, and this coupling- IOO piece has a `passage which in operation is connected to any suitable source of supply for fluid under pressure and communicates with a valve 24, designed to be oscillated within the bushing 21. Said bushing is formed with a shoulder or inwardly-projecting flange adjacent to its flange 22, and the valve 24 is shaped to conform to such construction, being so made that its body projects beyond the end of the bushing for the reception of a two-armed piece or fork 26, keyed thereto by means of a pin 25 and so placed as to extend into the path of motion of a projection 27 from the intermediate portion 6 of the plunger. The valve has init two independent passages 28 and 29, connected to the source of supply andto the exhaust, respectively,and each openingr upon the cylindrical surfacelof the valve, as shown in Fig. 3, in such manner as to operatively coact with openings 30 and 31 in the bushing 21.

In operation any device or apparatus designed to be rotated (in the present instance a drill) is fixed to the member 13 in any of the well-known ways, and there are, if desired, handles, as shown in full lines at 32, fixed to the bushings 3 and 4, whereby-the motor may be held. Fluid under pressure is admitted to the valve-chest through the coupling-piece 23 and passing into the channel 28 of the valve 24 ilows, when the parts are in the positions shown in Fig. 3, through the opening 3l of the bushing 21 into the port 18 and through the opening in the bushing 3 into the clearance-space between the end of said bushing and the plunger. The resultof this admission of iluid is to force the plunger toward the open end of its cylinder-bushing 3, such action turning both of the arms 10 on their pivots 9 and causing the pin of the lever 12 to be moved in the slot of the arm 10 outwardly toward the pivot thereof,consequently placing said lever in such position Within the annular cavity of the member 13 that it slips through the same for a limited distance. The motion of the arm 10a on its pivot will cause the projection 11 of the lever 12a to move t0- ward the plunger, thereby causing said lever to grip or jam between the inner and outer faces or sides of the cavity 13a and causing a partial revolution of the member 13 as the plunger 5 is moved. Just before said plunger arrives atl the end of its stroke toward the bushing 4 the projection 27 on its intermediate section 6 strikes one arm of the fork 26 and moves it so as to oscillate the valve 24, so that the opening 31 in the bushing 21, port 18, and the interior of the bushing 3 are placed in communication with the exhaust through the passage 29 of said valve. At the same time the opening 30 in the bushing 21, port 9, and the interior of the bushing 4 are placed in communication with the source of Huid-supply, with the result that the direction of motion of the plunger is reversed and is at the proper time driven toward and into the bushing 3. Such action causes the lever 12 to grip the sides of the cavity 13a, While the lever 12a is moved backwardly, so that it passes through the said cavity without gripping the walls thereof. The member 13 is thus intermittently rotated, being given two impulses in the same direction for each complete cycle of movements of the plunger, the power being transmitted through the clutching device formed by the arms 10 and 10a, levers 12 and 12a, and the gripping portion of the element 13.

If desired, I may provide any desired form of shoes or gripping-pieces 33 on the grippingfaces of the levers 12 and 12a, thereby preventing excessive wear of these parts.
